Nature's mechanisms for leaching and remobilising metals. This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and frac ....Nature's mechanisms for leaching and remobilising metals. This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and fractures. This project integrates innovation in geology, chemistry, and mineral engineering, and will deliver mineral-scale reaction models that will increase efficiency of in-situ mining and leaching technologies. Knowledge generated can be applied to improve mineral exploration, mining, and processing, contributing to unlocking billions of dollars’ worth of resources tied up in low grade, mineralogically complex ores.Read moreRead less

Rock slope instabilities present grave risks to life and to the serviceability of major Australian infrastructure such as mines, roads and railways, and to coastal recreation areas. This project aims at developing tools for the quantitative risk assessment of fractured rock slopes based on rigorous rock mechanics, numerical methods and probabilistic methods.
The research outcomes will improve our understanding of natural and engineering rock slopes, reduce the uncertainties in the prediction of the safety of infrastructures, and thus minimize the loss and damage. The research outcomes can also be used to maintain workplace safety in mining environments and avoid disruptions to production.

Molecular forces: in colloid science, complex fluids and living matter. The physical chemists; and the biologists, soil scientists and engineers who need them, have lived in parallel universes. Despite claims for relevance, the standard text book chemistry is unsatisfactory in a myriad industrial and basic applications. Identification of where theories went wrong has been made.

The physical chemists; and the biologists, soil scientists and engineers who need them, have lived in parallel universes. Despite claims for relevance, the standard text book chemistry is unsatisfactory in a myriad industrial and basic applications. Identification of where theories went wrong has been made. The repair of current theories will provide better predictive experimental design principles that get to real world solutions faster. There is a genuine paradigm shift in progress. Redressing deficiencies of present theories will provide a better intuition for scientists who need a predictive intuition from physical chemistry for optimal experimental design.

Enzyme-Mediated Machining of Chelators to Bind and Recover Valuable Metals. Metals are critical components of electronic devices and electrical products. Rapid disposal cycles create a major problem in managing e-waste metals and identifies an opportunity in the circular economy for recovery and re-use. Organic compounds that bind metal ions (chelators) are useful but could be improved to select a target metal from a mixture. This project aims to dissect a method used by bacteria to biosynthesiz ....Enzyme-Mediated Machining of Chelators to Bind and Recover Valuable Metals. Metals are critical components of electronic devices and electrical products. Rapid disposal cycles create a major problem in managing e-waste metals and identifies an opportunity in the circular economy for recovery and re-use. Organic compounds that bind metal ions (chelators) are useful but could be improved to select a target metal from a mixture. This project aims to dissect a method used by bacteria to biosynthesize chelators and hijack this to bioengineer new classes of chelators. Outcomes include new chelators and advanced knowledge of metal selectivity, with potential environmental and economic benefits arising from recovery of valuable metals. The project will benefit chemical biology research training for real-world applications.Read moreRead less

Multiscale modelling of multiphase interactions in shale gas reservoirs. As conventional oil and gas become depleted in most of the producing basins, extraction of unconventional gas trapped in shale formations needs to become more viable. Since Australian shales have different characteristics from North American ones, the existing knowledge cannot be directly applied. We aim to develop a novel multiscale framework for deep understanding of the complex multiphase interactions in shale gas reserv ....Multiscale modelling of multiphase interactions in shale gas reservoirs. As conventional oil and gas become depleted in most of the producing basins, extraction of unconventional gas trapped in shale formations needs to become more viable. Since Australian shales have different characteristics from North American ones, the existing knowledge cannot be directly applied. We aim to develop a novel multiscale framework for deep understanding of the complex multiphase interactions in shale gas reservoirs. The outcomes will not only enable us to effectively assess the viability of gas extraction from Australian shale reservoirs with accurate long-term production forecasting, but help to develop strategies to effectively extract this relatively low carbon-emitting fossil fuel in the transition to a renewable economy.Read moreRead less
Fear and licensing in Australia: Investigating the social licence to operate of an emerging coal seam gas industry. Australia’s nascent coal seam gas (CSG) industry is the site of substantial social tension. For some the industry can transform and safeguard national energy sources and fuel booming Asian exports. For others it damages both the environment and communities. This tension is vividly expressed by local protests and regulatory bans. Communities, mining companies and government invoke a ....Fear and licensing in Australia: Investigating the social licence to operate of an emerging coal seam gas industry. Australia’s nascent coal seam gas (CSG) industry is the site of substantial social tension. For some the industry can transform and safeguard national energy sources and fuel booming Asian exports. For others it damages both the environment and communities. This tension is vividly expressed by local protests and regulatory bans. Communities, mining companies and government invoke a 'social licence to operate' as fundamental to industry viability. This landmark project explores the concept of a social licence to operate in Australia's CSG industry to tease apart the dynamic risks, opportunities and tensions at work between corporations, rural and regional Australian communities and government, and offers policy and practice recommendations.
